3 Claims. (01. 248 -16 This invention relates to fans, and, more particularly, to the means for mounting fans on a support for universal movement. I I

This application is a division of my 'copending application Serial No. 155,673, filed July 26, 1937, now Patent No. 2,192,811 granted March 5, 1940. In mounting fans for circulating air, it is highly desirable that they be capable of universal adjustments so that the air can be directed to the desired location.

In view of the fact that the fans rotate at relatively high speeds, the mounting means must be sturdy and at the same time properly balanced so that the motor at these speeds will be securely held and will not cause any undue vibrations.

Accordingly, the present invention provides a mounting means for the motor by which the motor may be universally adjusted on the supporting means and which forms a sturdy support for the motor to hold it against vibrations.

In the preferred form of the invention, a supporting plate is provided with ears extending at each side thereof for a substantial portion of its length, which ears are secured to the motor casing whereby the plate is firmly anchored thereto.

One end of the plate is provided with an aperture to form a socket to receive the ball of the rigid supporting means for the fan. The other end of the plate is provided with a portion against which one end of a clamping plate rests. The clamping plate is provided at the other end with a portion adapted to engage the undersurface of the ball. and a screw is passed through a clamping plate and threaded to the supporting plate to draw the two plates together in locking relation with the ball. The clamping plate is reinforced so that it will not bend when the screw draws the plates together.

By loosening the screw, the gripping action of the clamping plate is released and the motor and the supporting plate attached thereto can be turned on the ball until the blades of the fan direct air to the desired point, whereupon the clamping screw is tightened and the motor will be held in place.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the drawing, in which:

Figure 1 shows a side elevational view of the fan and mounting.

Fig. 2 shows a bottom plan view of the motor, with the supporting member and ball removed.

According to the present invention, the fan comprises a motor 20, having a hub 2| secured .stream can be directed as desired, a novel mounttoithe drive shaft thereof. The hub has a plurality of fan blades 22 radiating therefrom and adapted, upon being rotated by the 'motor, to create a stream of air. a

In orderto mount the motor so that the air ing means is provided which comprises-asupport- .ing plate 23 having cars 24 turned, up from the (sides thereof intermediate its'ends; As shown,

these ears extend for substantially the major portion of the plate and are secured to" the motor casingas at 25 by welding or in any other manner sothat they securely anchor the 'plate in place and in spacedrelation:withtheundersurface of the motor; r I

One end 23a of the plate is provided with an aperture 26 adapted to receive the supporting means,herein illustrated as a rigid supporting rod 21 which is. suitably secured in any manner and having aball-like member. 28=-at the end thereof. The ball is positioned in the aperture 26 and is of such a size that the plate engages the upper surface thereof. The other end of the plate 23b forms a bearing surface for a clamping member 29 for holding the plate on the supporting member or means 21.

While the clamping member may take various forms, in the preferred form of the invention it is? formed as a substantially L-sh-aped bracket and has one end 29a bearing against the portion of the plate 23b, and its other end 29b is provided with a ball-receiving opening, herein illustrated as a U-shaped opening 30 (Fig. 2), forming a forked end on the clamping plate which will readily pass under the ball so as to engage the undersurface thereof. 3

The clamping member or plate may be secured to the supporting plate by suitable means. In the preferred form of the invention, a screw 3| is passed through an opening in the clamping plate intermediate its ends and is threaded into the supporting plate at a point located between the ears 24 so as to cause the clamping plate to pivot about the end 29a thereof and draw the ball-engaging portion 2% thereof into tight engagement with the undersurface of the ball and also draw the supporting plate into tight engagement with the upper surface of the ball so as to securely clamp the ball between the two ballengaging surfaces and hold the motor in adjusted position thereon.

In order to prevent the clamping plate or bracket from bending when the draft means is tightened up, the present invention provides reinforcing webs 32, as shown in Fig. 1, located on the sides of the plates so as to join the legs of the L. These webs together with the'intermediate plate form a channel member which efiectively prevents any bending of the L-shaped bracket as it is moved into clamping relation with the ballby the screw which applies the clamping force intermediate the ends thereof;

The supporting plate is held against bending by the ears 24.

As will be seen in Fig. l, the ears 24, by-which housing, extend for a substantial length {along the sides of the plate and connect the supporting plate to the motor at a point adjacent the connection of the supporting plate-withthe ball;

This provides a sturdy and balancedconstruction which will hold the motor to the support without undue vibration.

10' the supporting plate is attached to the motor being disposed in spaced relation with the surface of the motor; supporting means having a ball thereon to be received in the socket; clamping means comprising an L-shaped bracket mounted on the plate with one end engaging the plate and 'thefother end engaging and cooperating with the ball to clamp the plate in adjusted position on the ball; and means intermediate the endsof the bracket for moving the lattertoward'said' plate, said L-shaped bracket being provided with side walls for reinforcing the Also, as shown in Fig. 1, the plate is-secured to the motor so that it is approximately at the j'ustablemountin'g.

Variations and modificatidnsflmay be, made withinthescope of this invention and portions pftheimprovements may be used without others.
